Vulnerability from fkie_nvd - Published: 2026-08-15 06:22 - Updated: 2026-08-17 06:18

Severity

9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: qede: fix off-by-one in BD ring consumption on build_skb failure qede_rx_build_skb() and qede_tpa_rx_build_skb() do not check for a NULL return from qede_build_skb(). When it returns NULL under memory pressure, the functions still consume a BD from the ring before returning NULL. The callers then recycle additional BDs, resulting in one extra BD being consumed (off-by-one). This desynchronizes the BD ring, which can corrupt DMA page reference counts and lead to SLUB freelist corruption. Commit 4e910dbe3650 ("qede: confirm skb is allocated before using") added a NULL check inside qede_build_skb() to prevent a NULL pointer dereference, but did not address the missing NULL checks in the callers, making this off-by-one reachable. Fix this by adding NULL checks for the return value of qede_build_skb() in both qede_rx_build_skb() and qede_tpa_rx_build_skb(), returning NULL immediately before any BD ring manipulation.

When it returns NULL under memory\npressure, the functions still consume a BD from the ring before\nreturning NULL. The callers then recycle additional BDs, resulting in\none extra BD being consumed (off-by-one). This desynchronizes the BD\nring, which can corrupt DMA page reference counts and lead to SLUB\nfreelist corruption.\n\nCommit 4e910dbe3650 (\"qede: confirm skb is allocated before using\")\nadded a NULL check inside qede_build_skb() to prevent a NULL pointer\ndereference, but did not address the missing NULL checks in the\ncallers, making this off-by-one reachable.\n\nFix this by adding NULL checks for the return value of\nqede_build_skb() in both qede_rx_build_skb() and\nqede_tpa_rx_build_skb(), returning NULL immediately before any BD ring\nmanipulation."
